What is PaaS ?
Platform as a Service (PaaS) is a kind of cloud computing model where the environment allows the creation of applications. It is well known for its speed and accuracy. The environment consists of resources such as servers, data centers and other equipment all which are virtualized.Â
How is PaaS deployed ?
For the purpose of deploying a PaaS, the developers can use either Private, Public or Hybrid cloud. Although PaaS offers many benefits to startup businesses, it aren't flawless. Similar to other systems, a PaaS too shares it own drawbacks. For knowing whether its worth investing, it is advisable to look at the advantages and disadvantages.Â
In this article, I will be concentrating on 6 Advantages and Disadvantages of PaaS | Drawbacks & Benefits of PaaS. At the end of this post, you will know the pros and cons of using PaaS.
Let's get started,
Advantages of PaaS
1. Cost
All the companies which uses PaaS enjoy low investment cost since it does not require hardware and software. There is no expense involved in setting up and maintaining the software. The software can simply be used without needing to invest in infrastructure.Â
Apart from installation cost, even the expense of developing and testing the apps are significantly reduced. Therefore, it is preferred most by companies with limited resources willing to lower their operating cost.
2. Availability
PaaS is made available to all the professionals irrespective of the location. As a result, the employees of an organization can communicate with each others using a single environment. For an example, different staffs involved in testing and maintenance can collaborate with each other to carry out their works from different locations. Thus, the PaaS is able to increase the employee productivity.Â
3. Scalability
The scaling mechanism behind PaaS makes it a reliable scalability solution. The environment used in a PaaS is highly scalable with resources and tools. The structure is flexible enough to allow business to expand without high investment. This is especially beneficial for small businesses looking to increase their resources and expand their service.Â
4. Productivity
The work environment provided by the PaaS is already existing. They offer a pre-defined business plan. Meaning, each project needs not to be implemented from the beginning. Thus, the users does not create their own to develop new applications. Users can follow a standardized technique for the application development.
5. Upgradeability
Updates are really necessary for PaaS solutions to keep up with the competition. If the updates are not given time to time, the users could constantly miss out new features and improvements. These updates always ensure that the applications are running in their latest versions. Now the updates are automatically delivered by the PaaS provider.
6. Platform Support
It is crucial for a business to develop apps that support wide range of devices and operating systems. PaaS developers always make sure that their apps are supported by different platform types. For this they use specific tools designed for this purpose. Thus, PaaS ensures compatibility.
Disadvantages of PaaS
1. Security
All the data of applications are stored inside the provider's cloud database. This brings up confidential issues since the private and sensitive information can be viewed by the provider. As a result, it is the responsibility of the businesses to secure their applications by selecting a trustworthy provider. Otherwise, the existing information could be at risk.
2. Control
Users lack some controls over a PaaS solution. It is dependent on the providers capabilities. For an example, whenever the provider increases their pricing scheme similarly the applications could become expensive too. Therefore, it is important to choose your PaaS provider wisely.
3. Reliability
PaaS solutions often face reliability concerns. When using PaaS, users must be ready to face frequent downtimes. There can be power outages, disasters or other misfortunes all which can lead to devastating consequences. This can impact both business operations and customers who use the application. As a result, the users must perform their own backups to avoid data losses.
4. Compatibility
Not all the components are cloud enabled. Whatever the products offered by the PaaS provider is customized themselves. Due to this the infrastructures may face compatibility issues in a new environment.Â
Most obviously contradictions can be seen when PaaS comes in contact with the existing development platform. Therefore, users must be ready to accept what providers choose to offer.
5. Integration
Similar to compatibility, each and every PaaS provider has their own integration process. Two different PaaS solutions cannot be integrated with each other. If tried contradictions can be seen. Moreover, once there is integration issues it is not an easy task to change the PaaS provider.
6. Locked-in Features
Some of the features offered by the PaaS may be completely irrelevant to the user. It can be a program, language or an interface that is locked-in. The users have no authority to change it. The only thing the users could do is either make changes to the application or rebuild it.
